About some features of filtration processes in anisotropic rocks

Authors: A.M. Svalov (Oil and Gas Research Institute of RAS)
Features of filtration flows in anisotropic media in conditions, when the anisotropy is related to the layered structure of the rock, are investigated. It is shown, that in this case the values of the minimum water saturation, necessary for the movement of water along and across the rock layers, are different. It is established, that the nonlinearity of the viscoplastic fluids filtration processes causes a more complex form of the Darcy law, differing from its representation in tensor form.
